* Partial ultimate pressure measured according to Pneurop 6602 specifications. It may vary if other oils are used (See page 67).
** These values are for pumps equipped with universal single-phase motors.
Note: The pressure measurements were made with a capacitive diaphragm pressure gauge measuring a total pressure in the absence of
a cold trap. Measurements using a Pirani type gauge can give different pressure values.
